Description

Technical Field

[0001] This invention relates to the field of quartz fire processing technology, and more specifically, to an improvement of a quartz plate angle adjustable positioning device. Background Technology

[0002] In the quartz welding process, two quartz plates need to be welded together at a preset angle. To ensure the dimensional accuracy of the welded quartz component, the two quartz plates must be stably positioned at an angle before welding. Currently, the industry commonly uses manual stacking and positioning of graphite blocks. Operators manually move the graphite blocks to adjust the relative positions of the quartz plates. The graphite block stacking structure is loose, and the angle relies on repeated fine-tuning by the naked eye, resulting in poor repeatability and inconsistency of angles among products in the same batch. Each time the welding angle is changed, the graphite positioning blocks need to be stacked and arranged again, which is time-consuming. There is no quantitative precision adjustment structure, and the angle is judged entirely by the operator's experience, resulting in low angle control accuracy and failing to meet the production requirements of high-precision quartz devices. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a quartz plate angle adjustable positioning device based on a lead screw fine-tuning mechanism, which has the following beneficial effects:

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] According to an embodiment of the present invention, a quartz plate angle adjustable positioning device based on a lead screw fine-tuning mechanism is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-6 As shown, according to an embodiment of the present invention, a quartz plate angle adjustable positioning device based on a screw fine-tuning mechanism includes a first quartz plate 2, a second quartz plate 5, a bearing base 10, an angle flipping assembly 20, and a lifting adjustment mechanism 30. The bearing base 10 serves as the overall tooling installation reference, and the first quartz plate 2 is horizontally fixed on the upper surface of the bearing base 10, forming a horizontal bearing reference surface for the first quartz workpiece. An L-shaped limiting baffle 3 is fixed to the side of the bearing base 10, and the height of the limiting baffle 3 is higher than the maximum placement height of the quartz plate to prevent the plate from sliding laterally during processing. The angle flipping assembly 20 is installed on the side of the bearing base 10.

[0030] The angle-flipping assembly 20 includes a fixed hinge 4, which is fitted with a positioning seat 41. The positioning seat 41 has a positioning groove, and the bottom edge of the second quartz plate 5 is inserted into the positioning groove to achieve side alignment. The bottom of the second quartz plate 5 is rotatably connected to the fixed hinge 4, and can be flipped around the hinge axis to change the tilt angle. The lower side of the second quartz plate 5 is supported by a rubber roller 6. The outer layer of the rubber roller 6 is covered with a silicone buffer layer, which makes soft contact with the quartz plate and will not scratch the workpiece when adjusting the angle.

[0031] The lifting and adjusting mechanism 30 is vertically integrated into the middle of the bearing base 10. The lifting and adjusting mechanism 30 includes a support plate 301, a connecting seat 302, a lifting platform 7, a lead screw 8, an axis bearing 9, a hand-cranked adjusting handwheel 101, and a locking assembly 1011. The two sides of the support plate 301 are fastened to the bearing base 10 through the connecting seat 302. Multiple sets of axis bearings 9 are vertically installed on the support plate 301. The lead screw 8 passes through the axis bearing 9 to achieve vertical guidance. Two sets of lifting platforms 7 are slidably mounted on the lead screw 8. Rubber rollers 6 are rotatably mounted on the top surface of the lifting platform 7. The top of the lead screw 8 extends out of the bearing base 10 and is equipped with a hand-cranked adjusting handwheel 101. Rotating the hand-cranked adjusting handwheel 101 can drive the lead screw to rotate, causing the lifting platform 7 to rise and fall vertically along the lead screw. The rubber rollers 6 rise or fall synchronously, pushing the second quartz plate 5 to rotate around the fixed hinge 4, continuously changing the welding angle between the two quartz plates.

[0032] An angle marking plate 11 is set on the side end of the bearing base 10 corresponding to the limiting baffle 3. The angle marking plate 11 is printed with scale values. Each scale corresponds to a set of fixed welding angles. When mass-producing workpieces of the same specification, the lead screw can be directly adjusted to the corresponding scale to quickly reproduce the target angle. Support feet are installed at the bottom of the bearing base 10 to adjust the overall level of the tooling.

[0033] The hand-cranked adjustment handwheel 101 is equipped with a locking assembly 1011, which includes a lead screw stop locking nut and a lateral tightening screw. After adjustment to the preset welding angle, the locking nut and lateral tightening screw work together to lock the lead screw height, limiting the vertical displacement of the lifting platform 7 and ensuring that the tilt angle of the second quartz plate 5 remains constant throughout the welding process. The hand-cranked adjustment handwheel 101 can be replaced with a manual adjustment knob or a servo drive motor to adapt to different usage scenarios in manual and automated production lines.

[0034] Working principle: The first quartz plate 2 is laid flat on the bearing base 10 to complete the horizontal benchmark positioning; the bottom edge of the second quartz plate 5 is inserted into the positioning groove of the positioning seat 41 on the fixed hinge 4 to achieve precise alignment of the sides of the two quartz plates; rotating the hand crank adjustment handwheel 101 causes the lead screw 8 to rise and fall vertically along the axis bearing 9, driving the two sets of lifting platforms 7 and rubber rollers 6 to move up and down synchronously; the rubber rollers 6 push the second quartz plate 5 upward and flip it upward around the fixed hinge 4, and the welding angle between the two quartz plates changes synchronously; adjust to the process according to the scale of the angle marking plate 11. The welding angle is preset, and the screw stop locking nut and lateral tightening screw of the locking component 1011 are tightened to lock the lifting height of the screw 8 and fix the tilt angle of the second quartz plate 5. After the angle positioning of the two quartz plates is completed, quartz welding is carried out. When processing products of the same specification, the screw 8 is adjusted to the corresponding scale position on the angle mark plate 11 by directly turning the hand crank adjustment handwheel 101. There is no need to repeatedly try to adjust the angle, and the repositioning is completed quickly. When changing to other welding angles, it is only necessary to unlock the locking component 1011 and turn the hand crank adjustment handwheel 101 to adjust the screw height. The outer silicone buffer layer of the rubber roller 6 is in soft contact with the second quartz plate 5, so the quartz light-transmitting surface will not be scratched during the flipping and angle adjustment process. The double set of symmetrical axis bearings 9 form a limit guide for the lifting platform 7, so the screw 8 does not wobble left and right when lifting, and the angle adjustment is linear and precise. The limit baffle 3 prevents the quartz plate from sliding outward and avoids the workpiece falling and being damaged. The two sets of lifting platforms 7 can independently adjust the support height to adapt to the processing of quartz plates of different thicknesses and sizes.
